W = KE = 1/2m(v2f-v2i) also known as D just took the test
Answer:
F = 200 N
Explanation:
Given that,
Mass of the object, m = 20 kg
The acceleration of the object, a = 10 m/s²
We need to find the force exerted by the object. The force acting on the object is given by :
F = ma
So,
So, 200 N of force was exerted by the object.
The work is done by the 50 N force is 200 J.
<h3>
Work done by the 50 N force</h3>
Work done = Fd
where;
- F is Force applied
- d is the displacement of the object
Work done = 50 N x 4 m = 200 J
Thus, the work is done by the 50 N force is 200 J.

In an animal there are many different ways energy can be transferred. Here are some ways:
When it eats food- mechanical to chemical
When it moves- potential to chemical to mechanical + kinetic
